When not in use, the support rod, the support leg and the upright post are mutually folded together; when in use, the support rod, the support legs and the upright posts are enclosed to form a triangle. However, this support structure has a disadvantage in that when the ground is rugged or has a slope, the support foot is not supported smoothly on the ground.

In order to solve the above problems, the present inventors have studied for a long time to develop a portable lamp, in which the height position of the lock assembly 400 on the stand 100 is adjustable by providing the lock assembly 400 between the support bar 200 and the stand 100, so that the position of the support bar 200 on the stand 100 can be adjusted, that is, the position where the support bar 200 is connected to the stand 100 can be adjusted according to the support of the support foot 300 on the uneven or sloped ground, thereby ensuring the support of the support foot 300 to be stable. Meanwhile, the lock assembly 400 is locked after position adjustment, so that the support stability of the support structure is ensured.

Referring to fig. 1 and 2, the embodiment of the present application provides a portable lamp, which includes a light source assembly (not shown) and a support structure 1000, wherein the support structure 1000 is supported on the ground, and the light source assembly is connected with the support structure 1000, so that the light source assembly can be supported by the support structure 1000.

In an embodiment, referring to fig. 1 and 2, the portable lamp includes a plurality of groups of support structures 1000, and the plurality of groups of support structures 1000 are sequentially connected in a circumferential direction to form a storage cavity. The light source assembly comprises a lifting column 2000 and a light source 3000; the bottom of the lifting column 2000 is connected with each supporting structure 1000, and the lifting column 2000 is supported by each supporting structure 1000; the light source 3000 is disposed at the top of the lifting column 2000, the lifting column 2000 can descend with the light source 3000 and be accommodated in the accommodating cavity, and the lifting column 2000 can ascend with the light source 3000 to support the light source 3000 at a certain height, so as to expand the irradiation range of the light source 3000.

In one embodiment, referring to fig. 3-5, a support structure 1000 includes a column 100, a support bar 200, a support foot 300, and a lock assembly 400; the upright post 100 is vertically arranged, and the light source component is connected with the upright post 100; one end of the supporting leg 300 is hinged with the bottom end of the upright 100, and the other end of the supporting leg 300 is used for being supported on the ground; one end of the supporting rod 200 is hinged with the supporting leg 300, and the other end of the supporting rod 200 is connected with the lock assembly 400; the upright post 100 is formed with a plurality of locking holes 110 sequentially spaced apart in the vertical direction; the lock assembly 400 is slidably disposed on the upright 100; the lock assembly 400 can slide down the column 100 under the weight of the support bar 200 and the lock assembly 400; the lock assembly 400 includes locking bolts 410 that are lockable in different locking holes 110.

Wherein, because supporting legs 300 and stand 100 are articulated to be set up, and the one end of bracing piece 200 is articulated with supporting legs 300, and the other end of bracing piece 200 is located on stand 100 through lock assembly 400 slip, consequently, when not using, can be with supporting legs 300, bracing piece 200 and stand 100 folding each other accomodate, portable and transport.

In use, support foot 300 and support bar 200 are sequentially rotated and extended from upright 100. During deployment of the brace 200, the lock assembly 400 slides down the column under the weight of the brace 200 and the lock assembly 400 itself. When the supporting leg 300 is supported on the uneven or sloped ground, the height or the inclination angle of the supporting leg 300 will be changed adaptively with the ground, and the position and the angle of the supporting rod 200 hinged to the supporting leg 300 are changed with the supporting leg 300, and the supporting leg 300 drives the lock assembly 400 to slide on the upright post 100 to adapt to the change of the supporting leg 300. After the support leg 300 is stably positioned, the support bar 200 is positioned, and the locking tongue 410 of the locking assembly 400 is locked in the corresponding locking hole 110, thereby ensuring that the support leg 300 can be stably supported on the ground.

In one embodiment, referring to FIG. 4, the lock assembly 400 further includes a resilient member 420; the elastic member 420 is in a compressed state in a natural state; the latch 410 is fastened in the lock hole 110 by the elastic pressure of the elastic member 420. Because the elastic member 420 is in a compressed state in a natural state, the latch 410 will be locked in the lock hole 110 under the elastic pressure of the elastic member 420 without external force driving; meanwhile, due to the elastic pressure of the elastic member 420, the locking tongue 410 cannot be separated from the locking hole 110, so that the lock assembly 400 is self-locked, and the end of the supporting rod 200 is locked on the upright post 100, so as to ensure the supporting stability of the supporting structure to the light source assembly.

In one embodiment, referring to fig. 4 and 5, the lock assembly 400 further includes a lock base 450 and an unlocking member 430; the lock base 450 is slidably disposed on the upright 100; the lock tongue 410 is rotatably arranged on the lock seat 450; the elastic member 420 is pressed and abutted between the lock base 450 and the unlocking member 430; the unlocking piece 430 is movably arranged on the lock seat 450; the unlocking piece 430 is movably connected with the lock tongue 410; the unlocking member 430 presses the locking bolt 410 against the elastic member 420 to lock the locking hole 110. The elastic member 420 is in a compressed state in a natural state, the elastic member 420 has elastic pressure on the unlocking member 430, and the unlocking member 430 transmits the elastic pressure to the locking bolt 410, so that the locking bolt 410 is kept buckled in the locking hole 110; when an external force applies an unlocking force to the unlocking member 430 opposite to the elastic pressure of the elastic member 420, the unlocking force overcomes the elastic pressure and pushes the unlocking member 430, and the unlocking member 430 transmits the pushing force to the locking bolt 410, thereby disengaging the locking bolt 410 from the locking hole 110.

In one embodiment, referring to fig. 4 and 5, the lock assembly 400 further includes a connecting rod 440; the elastic member 420 is a linear expansion member; the unlocking piece 430 is arranged on the lock seat 450 in a sliding way; one end of the connecting rod 440 is hinged with the unlocking member 430, and the other end of the connecting rod 440 is hinged with the locking bolt 410; the connecting rod 440 can drive the locking bolt 410 to be buckled in the locking hole 110 or to be separated from the locking hole 110 under the driving of the unlocking member 430. In this embodiment, since the elastic member 420 is a linear expansion member, the elastic pressure acting on the unlocking member 430 is a linear pushing force, so when the unlocking member 430 is slidably disposed on the lock base 450, the elastic pressure can be fully exerted on the linear sliding of the unlocking member 430, and the smooth sliding of the unlocking member 430 is ensured; in addition, since the unlocking member 430 is a linear motion, has a unidirectional motion component, and the locking bolt 410 is a swinging motion, has a motion component in two directions, when the unlocking member 430 is directly hinged to the locking bolt 410, the unlocking member 430 cannot supplement the two-direction motion of the locking bolt 410, and the connecting rod 440 is provided, so that the linear pushing force of the unlocking member 430 can be transmitted to the locking bolt 410 through the connecting rod 440, and the swinging force of the locking bolt 410 can be compensated through the connecting rod 440. It should be understood that in other embodiments of the present application, the lock assembly 400 may not include the connecting rod 440, but the unlocking member 430 may be directly hinged to the locking bolt 410, where the unlocking member 430 may be configured to swing on the lock base 450, which is not limited herein.

Alternatively, the elastic member 420 is a compression spring.

In one embodiment, referring to fig. 4, the connecting rod 440 is V-shaped hinged with the latch bolt 410; the hinge of the connecting rod 440 and the latch 410 is disposed near the latch hole 110; the connecting rod 440 and the V-shaped opening of the locking tongue 410 are disposed opposite to the locking hole 110.

Meanwhile, since the V-shaped openings of the connecting rod 440 and the locking bolt 410 are disposed opposite to the locking hole 110, that is, the connecting rod 440 and the locking bolt 410 are disposed obliquely with respect to the surface of the upright post 100 on which the locking hole 110 is formed. When the elastic member 420 pushes the unlocking member 430, the unlocking member 430 drives the first hinge point of the connecting rod 440 to move toward the fourth hinge point 412 of the locking bolt 410, thereby pushing the second hinge point of the connecting rod 440 to move toward the locking hole 110, and then pushing the third hinge point 411 of the locking bolt 410 to swing around the fourth hinge point 412, so that the hook 413 is buckled into the locking hole 110. That is, through the above structural design, when the elastic member 420 is in a natural state, the locking tongue 410 is just buckled in the locking hole 110.

In one embodiment, the direction of expansion of spring 420 is parallel to the sliding direction of lock assembly 400 on post 100. Specifically, when the upright post 100 is vertically disposed, the extension direction of the elastic member 420 is a vertical direction, and the elastic member 420 has a vertically downward pushing force on the unlocking member 430, so that the locking bolt 410 is locked in the locking hole 110.

In one embodiment, referring to fig. 4 and 6, the latch bolt 410 includes a hook 413 capable of being fastened in the lock hole 110; the hook 413 includes a first guide surface 4131 and a second guide surface 4132 that are oppositely disposed along the extending direction of the column 100; the first guide surface 4131 and the second guide surface 4132 are connected in a V-shape. In this embodiment, the hook 413 is V-shaped, so that the hook 413 can be conveniently and quickly locked in the lock hole 110, and the first guide surface 4131 can also serve as a guide function when the hook 413 needs to be withdrawn.

In one embodiment, referring to fig. 4 and 7, the unlocking member 430 is formed with a receiving groove 431; the elastic member 420 is a cylindrical compression spring; one end of the elastic member 420 is inserted into the accommodating groove 431, and the other end of the elastic member 420 is fixed on the lock base 450; when the elastic member 420 stretches and contracts, the unlocking member 430 can be driven to slide on the lock base 450 in a straight line.

In one embodiment, referring to fig. 4 and 7, a toggle portion 432 is formed on the unlocking member 430 for toggling to slide the unlocking member 430 on the lock base 450. When unlocking, only the toggle part 432 is pushed by a hand or a tool, the elastic pressure of the elastic piece 420 can be overcome to push the unlocking piece 430 to move towards the elastic piece 420, so that the connecting rod 440 drives the lock tongue 410 to reversely rotate, and the lock tongue 410 is driven to withdraw from the lock hole 110; the operation is simple and convenient.
